The current aircraft structures tend to increase the proportion of integral structure parts. One main advantage is the cost, through a reduction of the assembly complexity. The fatigue behaviour of integral structures is also improved due to a reduct

This paper investigates the precipitation microstructures in aluminium alloys 7040 and 7050 (Al - Zn - Mg - Cu variants) as a function of quench rate and aging treatment, and the associated compromise between yield strength and fracture toughness. Th

The fracture behaviour in tension of an Al-Mg -Mn alloy has been investigated. At high temperatures and strain rates, intergranular brittle fracture is observed along with cleavage fracture. Intergranular fracture is related to local melting at the g

The fracture behavior of the 5383 aluminum alloy is investigated at high temperature (490–560 °C) and high strain rate (l0−2–25 s−1) by the secondary tensile test. A dramatic decrease of ductility is observed at all temperatures for the high

New aluminum alloys for aircraft structures have been introduced recently. These new alloys are designed in such a way as to improve the weight efficiency of the structure. A good understanding of the loading of the different airframe parts is needed

Alloys of the Al-Mg-Si-Cu series like AA6056 are good candidates for welded fuselage panels. The first part of the paper recalls the main metallurgical influences on final properties (mechanical strength, damage tolerance and intergranular corrosion

An attempt was made to predict the variable amplitude fatigue crack growth performance of aluminium alloys using existing simulation software. The experimental basis for validation consisted of variable amplitude tests for a large transport wing spec
